Can the rake overlay on actions be disabled?

Can the rake overlay be disabled?   
Expect this can be done per diagram.

Background

I have activities and actions.
When I create an activity diagram, I do the following:

• I add new actions to the diagram (no rake overlay), and/or
• I add an action as an invocation of an existing activity.  In this case the rake overlay is added.

Uhm, what is a rake overlay?

I updated the original post. 

From another post:

The official word (UML 2.2 Superstructure, section 12.3.14):

"The call of an activity is indicated by placing a rake-style symbol within the symbol. The rake resembles a miniature hierarchy, indicating that this invocation starts another activity that represents a further decomposition."

No, not really. The rake tells that it's a call action. You can however place an atomic action which is no call. That will display without the rake.
